SPRING BED OR BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 332,082, dated December8, 1885.

Application tiled March 6, 1985.

To all whom it may concern,.-

Beit known that we, EDWIN A. JEFFERY and FRANK M. J EFFERY, bothcitizens of the United States, and residents of Jersey City, Hudsoncounty, New Jersey, have invented certain Improvements in Spring Beds orBed- Bottoms, of which the following is a specification.

Our invention relates to that class of spring beds or bed-bottomsusually made wholly of metal, which comprise a series of slats, on whichthe springs are mounted, said slats being connected and distanced bylinks. It has been common to make the slats of thin steel strips orplates, to mount the springs on these, and to connect the springs attheir tops by chains. It has also been common, as shown in a formerpatent to E. A. Jeffery, No. 245,174, to connect the slats by linkshinged to the slats and at their middles, and provided with lockingdevices to make them rigid when the bed is in use. Such beds have alsohad top side slats mounted on the marginal rows of springs. These haveformerly been made of thin steel plates, but in a pending applicationofours we have shown a top side bar made from'a cylindrical steel rod orwire.

We are aware that the springs of a springbed have been connected attheir bottoms by wire slats or base-pieces common to two or more springsand arranged to rest on the ordinary slats of a bedstead; and we arealso aware that it has been proposed to connect together thehour-glass77 springs, so-called, of a spring-bed in groups, and connectthe springs of each group together at top and bottom by inner and outerbands or hoops formed of steel Wire and secured to the end convolutionsof the springs by clips. Our construction differs from these, as will beexplained.

The object of our present invention is to provide a light, substantial,and economicallyconstructed bed, made wholly of metal and capable ofbeing rolled up or collapsed, as desired. It comprises a novel form ofslat to support the springs, constructed of two parallel rods, usuallyof steel, and novel clips for securing the springs thereto; a novel formof top side bar constructed of two parallel rods, usually of steel, andnovel clips for securing said barv to the tops of the marginal SerialNo.157,893. (No model.)

springs, a novel form of link for connecting the slats and novel clipsfor hinging said links to the slats.

Our invention will be hereinafter more fully described, and its novelfeatures carefully defined in the claims.

In the drawings which serve to illustrate our invention, Figure l is aplan view on a small scale of our improved spring-bed as a whole. Inthis ligure we have only indicated the position of some of the springs.Fig. 2 is a plan view on a much larger scale of one corner of the bed.Fig. 3 is a sectional elevation of a part of the bed, beingsubstantially that part shown in Fig. 2. Fig. 4 is a crosssection of thelink, taken in the plane indicated byline 4 4 in Fig. 2. Fig. 5illustrates the folding of the hinged link when the bcd is collapsed.the bridge-clip for securing a spring to a slat. Fig. 7 is a plan andelevation ofthe bridge-clip for securing the top side bar to themarginal spring. Figs. 8 and 9 illustrate the lockinghinge which couplesthe two parts of a link between the slats. Fig. l() illustrates more indetail the construction of the slat and side bar of two pieces. Figs.11, 12, 13, 14, and l5 illustrate modifications, which will behereinafter described.

Referring first to Figs. 1 to 10, A A are the slats on which the springsare mounted. Each slat is made up of two wires or rods, a a, arrangedsubstantially parallel and extending the length of the bed. Y

Fig. 10 illustrates the preferred mode of constructing the slat, whichis by forming Fig. 6 is a plan and section of bends a in the two rods a,and securing these at the joints a2 by clips that will be hereinafterdescribed.

B B are the springs, of the usual construction, mounted on the slats A.

C is the bridge-clip for securing the spring to the slat. This is showndetached in Fig. 6. It is usually made of malleable iron, and isprovided with two loops or eyes, l l, through which the rods a a arethreaded, and a T-threaded stud, 2, to secure the spring in place. rPhespring has, at the bottom, a U-shaped loop, 3, bent in its end, whichembraces the neck of the stud 2, and the wings or clips on the stud arethen clinched down IOO over the loop 3, as seen in Fig. 3. This clip Cis arranged to embrace the rods a at the joints a2, and thus secure themrigidly together.

.D is the hinging-clip for the Slat-link. This is best seen in Fig. 5.It is usually made of malleable iron, and has loops or eyes 4 4, throughwhich the rods a a are threaded, as in the case of clip C. On its tcp isformed an elongated loop or eye, 5, to Aform a keeper to receive thehinging branches of the link. All of these clips are secured in place-onrods a a by compression or setting in with a punch, by preference; butother means, as soldering,may be employed, if preferred.

E is the slatconnecting link. This link comprises two bent-wiresemi-links, b b',v provided at their ends with hinging branches c c benton them at the proper angle. branches have bearings in the clips D D.Between the slats A the two parts b b are hinged together by ahinge-lock, d, the elements of which are shown detached in Figs. 8 and9. We will describe this lock, referring to Figs. 2, 3, 4, 8, and 9.

7 is the lower plate, (shown in plan and elevation in Fig. 8,) and 8 isthe upperplate. (Shown in plan and elevation invertedinFig. 9.) Theseplates are almost exactly alike, eX- cept that they are reversed, andwhen put together, as in Figs. 2, 3, and 4, they are secured by rivets.We usually form studs 9 on one plate, and holes 9'on the other plate, inorder to effect the riveting without the necessity of using extraneousrivets. When the lock is made of malleable iron, these studs will rivetdown properly. In both plates of the lock are formed half-round grooves10 10, which are shaped to receive and fit the bight of semi-link b, sothatwhen the two plates are riveted together the lock d will vbe rigidlysecured to this part; and in both plates are also formed haliroundcross-grooves Il 11, to receive the bight of the semi-link b. Thisconnection forms the hinge in the link, and is usually arranged midwaybetween the two slats. On the free projecting end of the lock is formeda T-head, 12, usually formed half on each plate, and in the ends of thelateral branches of this head are formed recesses 13 13, to engage thetwo branches of the semi-link b', and form a lock or fastening. As thesebranches of the link are somewhat elastic, the locking is effected bysimply pressing down the T- head 12, when inclines 14 14 (seen in Fig.4,) take between the branches of semilink b and wedge them apart untilthe head has descended far enough for them to spring into recesses 13.The link-hinge will then be locked and the link rigid; but by anexertion of a little force the branches of the link may be againdisengaged from the recesses 13, when the link will turn on its threehingesends and iniddle--and the slats may be brought together, as seenin Fig. 5. This enables the bed to be collapsed.

Th ese slats, as in Fig. 11.

In order that the slats may be brought close together, as in Fig. 5, weprefer to give the lock d the angular form seen in the several sideviews.

F is the t-op side bar. This bar we also construct of two metal rods, ee, usually of steel,

arranged substantially parallel and connected by bridge-clips. As thisbar is a counterpart in construction of the slat A, Fig. 10 will serveto illustrate the form of its rods e e. The bar is mounted on andsecured to a marginal row of springs.

G is the clip which is employed to connect and distance the two rods e eof the bar F. This clip is shown in plan and elevation detached in Fig.7, and in plan and elevation applied in Figs. 2 and 3. It has two eyes,15 15, through which the rods e c of the bar are threaded, and clips 1616 to embrace the wire of the spring B, and be clamped down thereon.

We will now describe the modification illustrated'in Fig. 11. This viewcorresponds to Fig. 2, and shows the slats A and side bar, F, composedeach of two straight rods, a a, and e e, respectively. These rods aredistanced, connected, and'braced by the several clips C, D, and G, asshown; but in addition to these we provide the slats A with end caps,D', which forni parts of the hinging-clips for the links E, or which mayform parts of the same when the links are set close to the ends of theconstruction has a socket-piece, H, at each end. These end sockets maybe secured by any wellknown means, as by soldering,for example.

The side bar, F, in this IOO Fig. 12 shows a modified form ofthe slat Aand bar F illustrated in Fig. 10. In this construction the ends of thesingle bent rod are brought together and united by being clamped withinone of the clips. In the case of the slat A we prefer to clamp the endsin a clip, C, that serves to secure a spring, B, to the slat. In thecase of the bar F, the ends may be clamped in a clip, G. Ve do not limitourselves to this mode of securing the ends. They may have a separatefasteningclip, or be scarfed and soldered together, or be otherwisefastened. It is obvious, however, that when we employ an endlesselongated loop of this kind for the slat and side bar we cannotconveniently form eyes in the clips C, D, and G. In lieu of eyes, weprovide clinchingclips, as shown in Figs. 13, 14, and 15, whichillustrate, respectively, the springattaching clip C, the hinging-clip Dfor the links, and the clip G for attaching the side bar, F, to thespring. In all of these views g g represent clinching-clips'to beclinched or hammered down on the rods.

The spring-attaching clip C shown in Fig. 13 differs from that shown inFig. 6 in having the T-head 2 made separate from the main IIO ciselylike one of the links E, being hinged, respectively, to the side bar andslat, and provided at its middle with a lock-hinge constructed likethelock-hinge d in the link E. This brace will, then, require no moreminute description.

Having thus described our invention, we claim- 1. In a spring bed orbed-bottom, the combination, with the springs, of the slat A, coinposedof two parallel cylindrical rods, and the clips C, provided withclinches for securing the springs thereto, and with eyes 1 1, to embracethe rods of the slat, whereby the said rods are distanced and rigidlyheld in position and the springs are mounted thereon at a point midwaybetween said rods, substantially as set forth.
